The passage describing Peter and Jesus’ interaction when He washes the disciples feet it’s humorous and a good parallel to how we sometimes choose to interact with God. When Jesus goes to wash Peter’s feet, he refuses. This is very much the way we sometimes react to God’s attempts to bless us. We feel unworthy and sometimes feel we need to earn it. Jesus takes the time to make Peter understand that he can not have a place in God’s kingdom if he doesn’t accept God’s gifts and blessings. While we may sometimes not be worth, Jesus’ mercy and grace are sufficient for us.
